Explain battery drain and Snowflake

[mongo]

Interesting, I didn't realize the pack was upside down.

Yeah, it's easy to get confused because that's pretty much what the 4680 Y pack looked like right side up.

I have not seen the snowflake once today driving all morning, not even a bit of blue on the bar, since updating to 2024.39.15 yesterday. Can anyone else confirm? It’s still below freezing, and yesterday before the update the snowflake and blue bar never went away the entire day. It was 10° colder yesterday but surely that didn’t make that much of a difference. People were seeing the snowflake in the 40s before.

I have a touch (1%) of blue, but no flake. 36F out currently.

2024.39.15 changed the thermal set points in the Cybertruck. The snowflake will now disappear at a pack temp of ~43F (coldest module), roughly 15 degrees (F) cooler than the previous set point.

11°F and unplugged last night got the snowflake back. 5-6% locked up in blue seems better than before the update when I often saw 10% locked. It was a few degrees cooler before though too.

I plugged into a 24A charger, and it limited to 16-17A for about 20 minutes heating the battery until the snowflake went away. It’s now heating the battery at 24A with no charging still, but unlocked 9 miles through the heating.

30 minutes in: Now charging full speed with no battery heating.

1 hour in: snowflake came back while charging. Still charging full speed
